When the car is moving, it has Kinetic Energy. As soon as the car entercount with the spring, its Kinetic Energy will transfer to Elastic Potential Energy.
<span>KE = EPE </span>
<span>1/2mv^2 = 1/2kx^2 </span>
<span>change the speed into m/s </span>
<span>50 km/hr = 13.9 m/s </span>
<span>1/2(1200)(13.9)^2 = 1/2k(2.2)^2 </span>
<span>now you do the math to solve for k.
k= 115926/2.42
K= 47903.30</span>
Answer:
33.33%
Step-by-step explanation:
The line of best fit for the data is represented by the equation y = 3x + 15.
At x = 4,
y = 3(4) + 15 = 27
At x = 7,
y = 3(7) + 15 = 36
We need to find the percent change in the total number of trees from x = 4 to x = 7.
So,

So, the required percentage change is equal to 33.33%.
